skcipher_enqueue(9)

💅 skcipher_enqueue — kernel API manual, but make it make sense

okay so bestie, welcome to skcipher_enqueue(9) — that's section 9 of the kernel API manual, iykyk, the one for the crypto driver girlies 🧚✨. This is the function that handles a skcipher encrypt or decrypt request, and honestly? She's the main character of the BCM crypto path.

---

🌸 NAME 🌸

skcipher_enqueue — literally handles your skcipher encrypt or decrypt request 💖

---

✨ SYNOPSIS ✨

int skcipher_enqueue (struct skcipher_request *req , bool encrypt );

---

🎀 ARGUMENTS 🎀

• req — the Crypto API request. that's the whole vibe right there, it's the request struct you're handing over 🫶
• encrypt — true if you're encrypting; false if you're decrypting. binary queen, no in-between 👑

---

🔥 RETURN 🔥

• -EINPROGRESS — if the request was accepted and the result will be returned asynchronously. she's taking her time and that's valid 💅
• < 0 — if there's an error 😭
